Wow, excellent work sir! Last 2 weeks I had a final-year project which required multiple pressure transducers. If I found your video earlier, the calibration for my sensors would have been much easier. But still, it can help me to improve my project's reliability. Thanks for the tips!

[@MikaelAbehsera]

Glad I could help! got any feedback on the way the video was filmed? anything you wish was done differently or better? thanks!

[@ethaninfante2768]

Thank you so much! I have a similar project using the pressure transducer replacing the arduino with an ESP32 but this video was a life saver!!

[@sNEAKYnIGHTmUPPET]

I would love to compare notes with you, as I am doing a very similar thing

[@MikaelAbehsera]

Glad it helped! thanks for the feedback

[@isov4345]

awesome..

[@cessromer7078]

Seems the pressure sensor especifications is for high pressure field and the power must come from arduino preferible than external power also for relay and water pump. However very nice set up.

[@BorisSiber]

thx 4 sharing

[@MikaelAbehsera]

Thx 4 watching

[@TalkieT]

I think you're lucky it worked at all without an explicitly common ground. You can power from external, but need to tie the sensor ground to the arduino ground. Looks like it was, but used the mains ground as the path

[@MikaelAbehsera]

ah, true. I will fix this for future videos but I know a lot of the time with arduino you can get away with it as i have. thanks.

[@MikaelAbehsera]

Made sure to fix this on the video I posted and gave you credit, thanks

[@thereallife9741]

thanks that fixed my problem

[@kinolar3210]

Thank you! I applied it to my course project

[@MikaelAbehsera]

Glad it helped! thanks for the feedback

[@countrymileoffroad8523]

hello, I have a couple questions, first off I am building an HHO torch setup, I currently have it all wired up for just an off switch, but I want it to turn off/ cut power when it hits 5psi, I will be running my Arduino into this torch build so I can set the parameters as I need. my biggest problem is I need the code to enter and I don't know how to, can you help me with the majority of the code? and I will figure out the rest.

[@tonybell9201]

Can this type of sensor also be used to caculate water depth if it was submerged to a specific depth?

[@hugocarrasco7734]

How would you make arduino control a vacuum sensor?

[@ryanlow604]

How long is the pressure sensor last in Working environment?

[@PauloAgustin-dt9mx]

will this work on omega px603 transducer. also do you have a copy of your code. Thanks

[@meesiphht2769]

I just wonder what good a setup like this is? I would think most would use the pressure sensor for a water level setup where they would want to turn a pump on and off according to a low/high pressure instead of what you're showing.

[@MikaelAbehsera]

its up to everyone to use it as they wish, I'm just trying to learn how these things wokr and share my experiences, since no one makes videos on it

[@JOSEBENJAMINROJASREYNOSO]

Where i can find the presure sensor?

[@josephdaquila2479]

Can you link the video before this? Or a part of this series? Im interested in seeing how you set up the relay with the pump

[@MikaelAbehsera]

Sure there’s actually a playlist of the series, once it’s gets hot enough we can go outside and run the full system !

[@josephdaquila2479]

​@@MikaelAbehseraoooh I'll be looking forward to that!

[@josephdaquila2479]

Is this rated for fluids other than water? EDIT: definitely think it will work well with fuel then! You're "hashtagging" ESP32, but you're using an arduino, so Im wondering if you just change the input voltage into the device for it to work with the ESP. 5 V down to 3.3 V? Because sensors are input devices to a microcontroller right? So the signal has to be what the device expects.

[@MikaelAbehsera]

This specific one is for cars and I think it can do gas / coolant / oil / air / water

[@MikaelAbehsera]

When you buy one check the what it can handle or it’s rating to make sure

[@josephdaquila2479]

Thank you Mikael! @@MikaelAbehsera

[@camaqazi]

hey is it possible to get the code for the pressure sensor ? Thanks!

[@maximsosnovski705]

2nd

[@JonasSebastianBarjauMateu]

Atmospheric pressure at sea level is aprox 15 psi. 0 psi would be absolute vacuum.

[@MikaelAbehsera]

yup silly mistake on my end, will be sure to mention it on the final project, thanks jonas.

[@JonasSebastianBarjauMateu]

Atmospheric pressure at sea level is around 15 psi. 0 psi would be absolute vacuum.

[@PHM_Tech]

No, absolute vacuum does not have any pressure because has no air molecules, vaccum pressure is measured in negative PSI on vacuum chambers (example)

[@JonasSebastianBarjauMateu]

@@PHM_Tech Riiiiight, ty

[@PHM_Tech]

@@JonasSebastianBarjauMateu You're welcome

[@alphanov2009]

What is the model of the pressures sensor please?

[@MikaelAbehsera]

Not sure on model but I just got it on Amazon, I’m pretty sure it’s the same as a generic car pressure sensor

[@josephdaquila2479]

Based off of this, maybe the answer to my question is yes? LOL@@MikaelAbehsera

[@vidotti911]

Would this work with esp32?

[@MikaelAbehsera]

yes, I try to make all my vids work on a range of microcontrollers including esp32

[@vidotti911]

Thanky you!@@MikaelAbehsera

[@rodwhittaker5704]

Do you have the link to the arduino code?

[@MikaelAbehsera]

was having some issues with sharing the code, can you join our discord? i can send it on there

[@i3dgearmarine908]

You have this wrong. The range of those pressure transducers if from 0.5V to 4.5V. .5V=0 psi and 4.5V=range of sensor. So you need to subtract .5 V and then divide by 4V. Any reading outside the range of .5 to 4.5 is an error. This is intentional with these transducers so you can detect a faulty sensor. Very misleading video showing people an incorrect calculation.

[@vitasartemiev]

That output range is only if input is rock solid 5v. In his example he had 0.45v at 1atm. Going by your equation we end up with negative pressure.
